Mokhtar Hosseiniamraei, 33, is alleged to have stabbed her with a pair of scissors after going to her workplace, according to court documents.

The papers say the couple were separated.

He was arrested that night and charged with her murder along with contravening a restriction in an Apprehended Violence Order (AVO).

He did not appear for the brief hearing at Parramatta Local Court on Sunday.

No bail application was made and bail was refused.

Hosseiniamraei, of Guildford West, is due to face Burwood Local Court on April 1.
